+1 to @sns Use one of the apps he describes. I used "TuneMyMusic" to transfer all my playlists, favorite albums, and tracks from Spotify to Tidal a couple years ago. Worked great and also offers the option of saving it as .csv files that can be opened in Excel or one of the free Excel compatible programs. I kept it just long enough to do my transfer, download those .csv files as a safety back up, and then cancelled my subscription.
I found it nice to have those files for going back and revisiting (finding!) albums I "favorited" long ago but might have nearly forgotten about. Gives me an incentive to listen to them again.
I figure the similar aps might also offer that same functionality. But TuneMyMusic worked fine.
